Jul.31 (GMM) Daniil Kvyat has admitted he has no future in F1 if he cannot end a major performance slump.

After a bad outing in Hungary, the young Russian's woes got worse at Hockenheim when he qualified between the Manors - half a second off Toro Rosso teammate Carlos Sainz's pace.

Kvyat was already struggling to bounce back from the disappointment of losing his seat at Red Bull earlier this year, amid the latest rumours that the energy drink company has decided to dump him altogether at the end of 2017.

"I am not having a good period and it seems there is no end," Kvyat is quoted by Russian media after qualifying at Hockenheim.

"I'm going through a hard time, it's not easy, but there's no excuse. We all have bad times, but if you don't do something about it, you just die."

Kvyat, 22, had said in a television interview straight after qualifying that he needs "more than the summer break" in order to recover from his slump.

Asked what he meant, Kvyat said: "I don't know what I need. I need a better feel from the car but I do not remember the last time I had it.

"I don't know what's going on."

Asked if the situation endangers his F1 career, he admitted: "At the moment it looks very bad, and if it goes on like this, I don't think anything good is ahead for me."

Finally, Kvyat was asked about the ongoing 'track limits' debate that is raging at Hockenheim, but he said: "I don't know. At the moment it's the last thing I'm worried about."
